Issaquah Depot is a former railway station located in Issaquah, Washington, listed on the National Register of Historic Places. It was built in 1889 as a passenger station and freight warehouse for the Seattle, Lake Shore and Eastern Railway (SLS&E), serving what was then known as Gilman, Washington (and as Squak Valley until 1888). The town was renamed Issaquah around the turn of the century. Only a few years after the depot's opening, in the 1890s, the SLS&E was taken over by the Northern Pacific Railway.[2]
